Chinese Tool Hacks Seized Phones to Extract Sensitive Data

Chinese Malware Massistant Targets Mobile Data

Security researchers have reported that Chinese authorities are utilizing a sophisticated malware tool called Massistant to extract data from seized mobile devices. Developed by Xiamen Meiya Pico, this tool allows authorities to obtain sensitive information such as text messages (including those from encrypted apps like Signal), images, location histories, audio recordings, and contacts.

Massistant operates on Android devices and is designed for forensic data extraction, necessitating physical access to the target device. Its widespread use raises significant concerns for both Chinese residents and travelers to China, as they risk having their devices confiscated and data collected. Kristina Balaam, a researcher at Lookout, warned, "I think anybody who’s traveling in the region needs to be aware that the device that they bring into the country could very well be confiscated and anything that’s on it could be collected."

The malware is installed on an unlocked device and works in conjunction with specialized hardware connected to a computer. Balaam noted that while Massistant has been found on user devices after police interactions, Lookout has not yet analyzed its desktop component or confirmed compatibility with Apple devices. The tool's installation leaves traces, allowing users to potentially identify and remove it, though by that point, the data has likely already been compromised.

Massistant is considered the successor to a previous tool known as MSSocket, also developed by Xiamen Meiya Pico, which holds a significant share of China's digital forensics market. The company has faced U.S. sanctions for supplying technology to the Chinese government. Balaam emphasized that Massistant is just one of many malware tools produced by Chinese surveillance tech manufacturers, existing within a larger ecosystem of spyware.

APT27 Hacking Campaign Targets U.S. Entities

The U.S. Department of Justice has unsealed indictments against two Chinese nationals, Yin Kecheng and Zhou Shuai, linked to a sophisticated hacking campaign targeting numerous U.S. companies and institutions. These individuals, associated with the Chinese government, are accused of participating in a long-term scheme to exfiltrate sensitive data and sell it for profit.

Yin and Zhou, connected to the hacking group known as APT27, have been implicated in cyber intrusions affecting a range of sectors, including technology firms, think tanks, and government agencies. The Department of Justice's coordinated effort highlights the Chinese government's role in fostering cybercriminal activity among its citizens.

The indictments reveal methods employed by APT27, which include exploiting network vulnerabilities and installing malware to maintain persistent access to compromised systems. These actions have resulted in significant financial damages and the loss of sensitive data.

The Justice Department's actions include the seizure of virtual private servers and domains linked to these hackers, underscoring the ongoing threat posed by state-sponsored cybercrime. U.S. Attorney Edward R. Martin, Jr. stated, “These indictments and actions show this Office’s long-standing commitment to vigorously investigate and hold accountable Chinese hackers and data brokers who endanger U.S. national security.”

CBP Seeks Advanced Digital Forensics Tools

U.S. Customs and Border Protection (CBP) is actively seeking proposals from technology companies for advanced digital forensics tools to analyze data on devices seized at the border. The agency is looking for capabilities to process text messages, pictures, videos, and contacts from smartphones and other electronic devices.

CBP currently uses Cellebrite technology for data extraction but aims to modernize its digital forensics program. The agency reported conducting searches on over 47,000 electronic devices in a recent year, indicating a growing reliance on digital data analysis for security purposes.

The request for information details specific requirements, such as identifying hidden languages in text messages and accessing encrypted messaging app chats. CBP's plans to enhance its digital forensics capabilities come amid increased scrutiny and reports of travelers being questioned about their devices.

Cellebrite's digital forensics tools, including its Universal Forensic Extraction Device, are designed for comprehensive data analysis. This technology enables users to filter and analyze large datasets, making it a crucial resource for law enforcement agencies.

National Guard Hacked by Salt Typhoon Group

A recent Department of Homeland Security memo revealed that the elite Chinese cyberspy group known as Salt Typhoon hacked a state’s National Guard network for nearly a year. This breach is part of a broader pattern of cyberespionage attributed to the group, which has previously targeted various U.S. entities.

The hackers allegedly accessed sensitive military and law enforcement information, compromising internal networks and potentially facilitating further attacks on other organizations. The extent of the data accessed is still under investigation, but the implications for national security are significant.

The memo indicates that Salt Typhoon has demonstrated the ability to infiltrate multiple organizations, raising concerns about the vulnerability of U.S. defense and law enforcement networks. The lack of conclusive evidence linking the group to the Chinese government continues to be a point of contention.

To learn more about this hacking incident, refer to the NBC News report and the DHS memo detailing Salt Typhoon's activities.
